Rochelle salt type crystals show ferroelectricity. Previously suggested model is little modified to explain ferroelectric behaviour of three crystals. Simple Green’s function approach is used to obtain normal mode frequency formula. This frequency is calculated for different temperatures for Rochelle salt crystal. Theoretical results are compared with others experimental data formulae for dielectric constant and spontaneous polarization are obtained. Values are calculated for Rochelle salt crystal and compared with experimental data of F. Sandy and R. V. Jones (1968).
